Taxonomic note

Ripiphoridae was historically treated as a of Meloidae (blister beetles) due to shared hypermetamorphic development, but is now recognized as a distinct within Elateriformia. The family contains approximately 400 worldwide, with Ripiphorus being one of the more species-rich in North America.

Life history context

Ripiphorids are among the most morphologically and biologically unusual beetles. First instar larvae () are typically mobile and seek out , while subsequent instars become more -like and sedentary within the host nest. This hypermetamorphic development is convergent with some Meloidae and (Strepsiptera are unrelated despite similar names).
